Summary
Proper battery maintenance is vital when MINI vehicles are in your center’s inventory. Allowing a vehicle’s low-voltage battery to drop below 12.0 volts (12.0 V) permanently reduces the expected battery life and can lead to premature failure. For vehicles equipped with high-voltage (HV) batteries, (Plug-in Hybrid Electric Vehicle (PHEV) and Battery Electric Vehicle (BEV)), improper maintenance or handling may lead to a discharged HV battery, requiring replacement. We provide a flexible battery maintenance system which every MINI dealer can use to meet their particular needs. This bulletin explains the Battery Charging Calendar (see attachment), charging system and battery voltage checking procedure below.
